Application-December 17, 1948,.Serial No. 65,869-

(Cli 217-4 This inventionrelates to building construction and" particularly is related to buildings made from logs.

This invention has certain new and novel improvements over my Patent No. 2,289,018 relating to Log house construction.

The primary object of this invention is to build a log house from half logs, the fiat part of the logs providing a relatively smooth interior finish.

A further object of this invention is to erect the logs in vertical order and providing simple means of securing the logs together and weather stripping the space between the logs by a seal that :will permit expansion and contraction of the logs.

A still further object of this invention is to provide a framework to which the logs are secured, said framework assisting in the carrying out of the method of joining and weather stripping the logs together.

These and other incidental objects will be apparent in the drawings, specification and claims.

Referring to the drawings:

Figure 1 is a fragmentary sectional view, taken through the wall of a building constructed from my new and improved half logs.

Figure 2 is a fragmentary detailed plan sectional view taken on line 2-2 of Figure 1, illustrating the method of erecting the logs, sealing the space between the said logs, and window and door casings.

Figure 3 is an enlarged fragmentary detail sectional view taken on line 33 of Figure l, illustrating the construction shown in Figure 2.

Figure 4 is a perspective view of one of my new and improved half logs.

Figure 5 is a perspective end view of the horizontal rail or gird for holding the logs together.

Figure 6 illustrates a preferred form of resilient member for maintaining the weather strip seal between the logs.

Figure '7 illustrates a partial log having a groove cut therein adapted to accommodate electric wiring.

Referring more specifically to the drawings:

My new and improved half log for the building of log houses is best indicated in Figure 4. The log is indicated by numeral I, having its natural state on one side and flattened on the opposite side as indicated by numeral 2. Each edge of the flat side of the log has a right angle groove 3 running longitudinal of the log.

Referring to Figures 1, 2 and 3, the logs l are erected vertically and are secured to the base plate 4 and the top plate 5 and are secured together. mid-way their lengths by special rails or girdsfiby'way' of nails 1. These rails or girds are 9; decided improvement over my'pres'entp'a'tentin regards to strengthening the" structure. These rails or girds also provide a base for securing inner finishing walls, such as panel boards, etc., to. Where inner walls are not used the inner flat surfaces 2 of the logs provide an attractive and smooth finish, which is an improvement over my above mentioned patent.

Relatively thin boards 8 are nested within the grooves 3 resting on the flat portion or leg 9 of the right angled groove 3. This board or strip bridges the space between the logs as well as providing a relatively tight weather strip seal when the said board is forced against the fiat portion 9 of the groove 3 by the action of the resilient units or springs in, best illustrated in Figures 2 and 3.

A longitudinal channel way I I is cut in the rails or girds 6 and is adapted to receive the resilient units [0, maintaining them in their proper position relative to the board or strip 8. The inner side of the board 8 which is oppositely disposed to the logs, presents a finished appearance to the inner walls of the building. This feature is especially important when no secondary finishing walls are being installed.

Referring to Figures 1 and 2, the window and door frames are grooved at l2 and adapted to receive the sealing boards 8 making a tight weather strip seal between the said frames and the log walls.

In Figure 7 I illustrate a groove 20 cut longitudinal of the flat surface of the log. The purpose of this groove is to provide space for electric conduits of the electric wiring system being in stalled in the building.

Although certain specific embodiments of the invention have been shown and described, it is obvious that many modifications thereof are pos sible. The invention, therefore, is not to be restricted except in so far as is necessitated by the prior art and by the spirit of the appended claims.

What I claim is:

1. A building wall construction comprising a plurality of vertically dis-posed logs in laterally spaced relation, each of said logs comprising a longitudinal portion of a whole log and having a fiat inner face with grooves along the lateral edges thereof, the grooves along the adjacent edges of adjacent logs defining a recess longidinally of said logs, a board freely seated in each of the recesses and spanning the space between said logs, horizontal rails secured to the flat inner faces of said logs in spaced relation, and springs between said rails and said boards for retaining said boards snugly against the faces of said grooves.

2. A wall construction as defined in claim 1 wherein said rails are provided with recesses on their log-engaging sides for receiving and anchoring said springs.

3. A wall construction as defined in claim 2 wherein said recesses are formed by grooves extending the full length of said rails.

4. A building wall construction comprising, in combination, a base plate member, a top plate member, a plurality of vertically disposed logs secured to said plate members in laterally spaced relation, each of said logs comprising a longitudinal portion of a whole log and having a flat inner face with grooves along the lateral edges thereof, the grooves along the adjacent edges of adjacent logs defining a recess longitudinally of said logs, a board freely seated in each of the recesses and spanning the space between said logs, horizontal rails secured to the flat inner faces of saidlogs in spaced relation, and springs between said rafls and said boards for retaining said boards snugly against the faces of said grooves.

5. A building wall construction comprising a plurality of vertically disposed logs in laterally spaced relation, each of said logs comprising a longitudinal portion of a whole log and having a flat inner face with grooves along the lateral edges thereof, the grooves along the adjacent edges of adjacent logs defining a recess longitudinally of saidlogs, a board freely seated in each of the recesses and spanning the space between said logs, a frame in the plane of logs and defining an opening in said wall, grooves in the outer sides of said frame, a board freely seated in each of said frame grooves and the adjacent edge grooves of adjacent logs and spanning any space therebetween, horizontal rails secured to the flat inner faces of said logs in spaced relation, and springs between said rails and said boards for retaining said boards snugly against the faces of said grooves.
